We've all seen the satellite images of Earth at night--the bright blobs and shining webs that tell the story of humanity's endless sprawl. These pictures are no longer just symbols of human impact, however, but can be used to objectively measure it, according to a study in the December 2008 issue of Geocarto International, a peer-reviewed journal on geoscience and remote sensing. Travis Longcore, a USC geographer and expert in light pollution, collaborated with an international team, led by...

Imagine descending in a submarine to the ice-cold, ink-black depths of the ocean, 800 meters under the surface of the Atlantic. Here the tops of the hills are covered in large coral reefs. NIOZ-researcher Furu Mienis studied the formation of these unknown cold-water relatives of the better-known tropical corals. Furu Mienis studied the development of carbonate mounds dominated by cold-water corals in the Atlantic Ocean at depths of six hundred to a thousand meters. These reefs can be found...

The U.S. Fisheries Service says it will increase its protection of elkhorn and staghorn corals in Florida, Puerto Rico and the U.S. Virgin Islands. The service, part of the National Oceanic and Atmospheric Administration, says new regulations prohibiting activities that result in death or harm to either of the threatened species become effective Nov. 21. "These corals were once the major reef builders in Florida and the Caribbean, but now more than 90 percent of their populations are...

New research in Australia has found disturbing new evidence to show that the world's coral reefs may be in more immediate danger than some experts previously considered. Australian scientists studied the effects of climate change and rising sea temperatures to find that these events may speed the process of coral bleaching, thus leading to the destruction of the world's reefs. "Previous predictions of coral bleaching have been far too conservative, because they didn't factor in the effect of...

Rare corals may be smarter than we thought. Faced with a dire shortage of mates of their own kind, new research suggests they may be able to cross-breed with certain other coral species to breed themselves out of a one-way trip to extinction. This finding, released by scientists at the ARC Centre of Excellence for Coral Reef Studies, has raised hopes for the ability of the world's corals to withstand the rigors of changing climates and human impacts, says lead author Zoe Richards. "Coral...

U.S. scientists say they observed significant recovery of an endangered coral reef when they managed the reef's diversity of fish. Professor Mark Hay and co-author Deron Burkepile of the Georgia Institute of Technology constructed 32 cages on a coral reef at Key Largo, Fla. Then into each 140-cubic-foot cage, Hay and Burkepile placed different numbers of two types of herbivorous fish. During the next 10 months they measured changes in coral cover and seaweed growth. The scientists...

Scientists are using satellites to expand a network to watch for ocean temperature increases that can harm fragile ecosystems worldwide. On Thursday, the National Oceanic and Atmospheric Administration said its Coral Reef Watch network had been expanded from 24 locations to 190 locations in the Florida Keys, the Caribbean, Australia, Hawaii, Indonesia, and in other areas across the globe. The organization monitors ocean temperatures in nearly a dozen coral reefs.  The larger, expanded...

Entertaining at home will become trendy in today's economy, and nothing brings people closer together than dinner. Always a good reason for guests, but what to put on that giant video screen of yours? NASCAR, rodeo, rock concert, football? That'll drive a wedge through your guest list. Instead try a subtle, soothing ambiance from HD2O(TM). Announcing the release of "HD2O - The Keys," totally underwater content for entertaining guests at home. The DVD is a 67-minute underwater journey to...

For endangered coral reefs, not all plant-eating fish are created equal. A report scheduled to be published this week in the early edition of the journal Proceedings of the National Academy of Sciences suggests that maintaining the proper balance of herbivorous fishes may be critical to restoring coral reefs, which are declining dramatically worldwide. The conclusion results from a long-term study that found significant recovery in sections of coral reefs on which fish of two complementary...

When reef fish get a mouthful of sand, coral reefs can drown. That's the latest startling evidence to emerge from research into the likely fate of reefs under climate change and rising sea levels, at the ARC Centre of Excellence for Coral Reef Studies (CoECRS). "We've known for a while that having a lot of sediment in the water is bad for corals and can smother them.  What we didn't realize is how permanent this state of affairs can become, to the point where it may prevent the corals...

Coral reefs are submerged structures consisting of calcium carbonate secreted by corals. Coral reefs are colonies of small animals found in marine waters that enclose few nutrients. The majority of coral reefs are constructed from stony corals, which then consist of polyps that come together in groups. The polyps are like small sea anemones, to which they are very closely related. Unlike the sea anemones, coral polyps secrete hard carbonate exoskeletons which provide support and protections...

Chalice Corals, are a family of stony corals in the Pectiniidae family. Members of this family are mostly colonial but at least one species, Echinomorpha nishihirai, is solitary. These corals are endemic to the Indian and Pacific oceans. Pectiniids have a number of different forms but are basically streamlined and smooth. Polyps are large and brightly colored and resemble those of members of the Mussidae family of corals. The polyps are only extended at night. Tentacles are translucent,...

Siderastreidae is a family of colonial, reef building stony corals. Members of this family include symbiotic algae in their tissues which help provide their energy requirements. The World Register of Marine Species lists 7 genera within this family: Anomastraea, Coscinaraea, Craterastrea, Horastrea, Psammocora, Pseudosiderastrea, and Siderastrea. Corals in this family vary in form and include massive, thickly encrusting, columnar, and irregular forms. Corallites are linked by flowing...

Horn corals, known as Rugosa or Tetracoralla, are an extinct order of coral that were abundant during the Middle Ordovician to Late Permian stages. They were known as horn corals because of a unique horn-shaped chamber with a wrinkled (rugose) wall. These mostly solitary corals often reached lengths of nearly 40 inches. However, some species could form large colonies. Rugose corals have a skeleton made up of calcite that is often fossilized. Like modern corals, rugose corals were...

Tabulata is a family of extinct tabulate corals. These corals lived entirely during the Paleozoic era, being found from the Ordovician to the Permian stages. There are about 300 known genera of tabulate corals, of which Aulopora, Favosites, Halysites, Heliolites, Pleurodictyum, Sarcinula and Syringopora are the most common in the fossil record. These corals were mostly found in the shallow waters of the Silurian and Devonian, after which, they became much less common. They became extinct...
